    Automatic Blow Off For A Conveyor

    So far it is not known if this is a professional Industrial/commercial bottling line, If so, I would expect some way of integrating it into the existing system, I can't see anyone designing something like this without some kind of allowance for future needs. Also are these empty bottles or...

    Automatic Blow Off For A Conveyor

    ++. To give a practical answer system details have to be known, Electronic, Electrical, Mechanical. Otherwise pure guess work.:rolleyes: M.

    Automatic Blow Off For A Conveyor

    What is meant exactly by 'No room for I/O'? You have run out of I/O? If so what is the present means of control? M.

    Issue in BLDC motor

    The Picmicro Picdem MC LV prototype manual may help in some way, this is the BLDC development board You may be able to down load the S/W also. the pdf is downloadable also from 51554b.pdf. M.

    Issue in BLDC motor

    BLDC are not 3 phase motors, although they are virtually both identical. BLDC only have 2 windings energized at any one time, as opposed to 3 phase, which is fed by three phase sine wave. They represent a DC motor turned inside out, Hence BLDC. The difference is also in the commutation. The pdf...

    Issue in BLDC motor

    To implement velocity control on a DC or BLDC motor requires some kind of feedback to the controller, from the Halls themselves other than for commutation or other means. M.

    Why does this lamp need a transformer?

    It is a starting choke for the lamp. Also improves power factor. https://www.quora.com/Why-the-power-factor-of-fluorescent-lamp-is-lagging M.

    Driving of 3 phase motor

    It sounds like you are describing a BLDC motor as these are generally the ones that use Hall effect sensors for commutation. In a BLDC motor only two coils are powered at any one time. There is generally three possible conditions, driving = wingdings powered, all off, and three bottom devices...

    Using An Oscilloscope

    The secondary is not referenced to ground so no point connecting the scope GND to it. If you isolate by using the transformer for the scope, the scope is no longer grounded, I prefer to galvanically isolate the circuit I am working on. M.

    Using An Oscilloscope

    The ideal is a 1:1 isolation transformer as it is possible to cause high current in the scope common lead if placed at the wrong point or cause a short circuit. M.

    Where to start

    I have never used Arduino but have used Picmicro extensively, if you are not comfortable with assembly you could graduate to C, Both have their plus and minuses. I tend to have stuck with assembly as that was my original teaching with micro's. PDP8's and 8085 etc. M.

    Hall effect switching info needed

    If you have nothing at the moment how did you arrive at 1/2 amp current draw? It seems you have taken on quite the task of designing a specialty coil with no prior experience. If the automotive injector falls within the realm, at least dismantling one would give you a little insight to the...
